EDWARD CLIFF, OF NEWARK, NEYV JERSEY.

CAR-TRU C'K.

SPECIFICATION forming part of Letters Patent No. 539,977, dated May 28,1895.

Application filed May '7, 1894- Serial No. 510,299. (No model.)

To aZZ whom it may concern.-

Be itknown that I, EDWARD CLIFF, of N ewark, in the county of Essex, inthe State'of New Jersey, haveinvented new and useful Improvements inCar-Trucks, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in street railway car trucks, andparticularly to the improved arrangement of the spiral springs toprovide an easier riding car and to prevent undue vibrations of theupper frame.

To this end my invention'consistsin the combination with the axle-box,lower frame, pedestal or yoke in the frame and the upper frame of thetruck, of projections on each side of the axle-box, vertical guide-postsheld in the yoke and passing through said projections, a spiral springbetween the box and the yoke, and one or more springs between the yokeand the said upper frame; and my invention consists in certain'othercombinations of parts hereinafter described and specifically set forthin the claims.

In the drawings accompanying this specification and forming a parthereof, Figure l isa side elevation of my improved pedestal or yoke,together with the neighboring parts. Fig. 2 is a top plan View of theaxle-box, taken on line mm of Fig. l; and Fig. 3 is a modified form andarrangement of the parts shown in Fig. 1.

Referring specifically to the drawings, A represents one of the carwheels; B, the axlebox; 0, the pedestal or yoke which is integral withthe end portion of the lower truck frame A, and A is the upper frame ofthe truck.

Heretofore the axle-box worked directly on thevertical sides of theyoke, but in my invention said vertical sides are separated widely toreceive projections B, B on the sides of the axle-box. Vertical bolts orguide posts, I), 19, pass through said projections, B, B, one on eachside of the axle-box and are held in place in the yoke and between thelatter and the detachable retaining bar, F, extending horizontallybetween the sides of the yoke and below the axle-box, and which can bedetached for the purpose of removing the said box from the yoke orframe. The axlebox with its projections slide on said guidesockets, e,e, for the lower ends of spiral springs, E, E, extending upward to thelower side of the upper frame, A, of the truck.

S ring sockets ee are secured to the u er 3 frame to receive theupperends of the springs, E, E.

In Fig. 1 the springs, E, E, are shown side by side above theprojections, B, B, on the axle-box but in Fig. 3 said springs are shownone within the other. i

I do not wish to limit myself to a plurality of springs between eachyoke and the upper frame, as a single heavy spring may be used alone,or, the inner spiral spring shown in Fig. 3 may be dispensed with, ifdesired.

This construction of yoke and axle-box togelherwith the arrangement ofspiral springs is designed more especially for use with my improved formof car truck having semi-elliptic springs, G, hung at each end betweenthe two frames, with or without a central semibut form the subjectmatter of an application filed September 8, 1893, Serial No. 485,l2l,andanother application filed herewith. I

Having described my invention, what' I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the axle-box, lowe frame, yoke in the frame, andthe upper frame of a truck, of projections on each side of the axle-box,vertical guide posts held stationary in the yoke and passing throughsaid projections, a spiral spring between the said box and the yoke, anda spiral spring between the yoke and the said upper frame, as set forth.

2. The combination with the axle-box, lower frame, yoke in the frame,and the upper frame of a truck, of projections on each side of theaxle-box, vertical guide posts held stationary in the yoke and passingthrough said projections, a graduated spiral spring between the said boxand the yoke, and a spiral spring between the yoke and the said upperframe, as set forth.

3. The combination with the axle-box, lower frame, yoke in the frame,and the upper frame of a truck, of projections on each side of theaxle-box, vertical guide posts held stationary in the yoke and passingthrough said projections, a graduated spiral spring between the said boxand the yoke, and a plurality of spiral springs between the yoke and thesaid upper frame, as set forth.

4. The combination with the axle-box, lower frame, yoke in the frame,and the upper frame of a truck, of projections on each side of theaxle-box, vertical guide posts held stationary in the yoke and passingthrough said projections, a spiral spring between the said box'and theyoke, a socket on the yoke to receive the upper end of said spring, apair of spiral springsbetween the'yoke and the upper frame, and springsockets formed on the yoke and upper frame to receive the ends of thelatter springs, as set forth.

5. The combination with the axle-box, lower frame, yoke in the frame andthe upper frame of a truck, of a semi-elliptic spring fulcrumed at itscenter upon the end of the lower frame and shackled at one end to thelower frame and at the opposite end to the upper frame,
